LANTERN.

SPECIFICATION forming part of Letters Patent No. 606,028, dated June 21 1898. Application filed November 6, 1897 Serial No. 657,590. (No model.)

To all whom it may concern.-

Be it known that I, EDWIN M. ROSENBLUTH, a citizen of the United States, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Lanterns, of which the following is a specification.

My invention relates to vehicle and other lamps or lanterns, and especially to the re-' fleeting devices or plates ordinarilymounted in and carried by them.

As is well known, in the continued use of lanterns, the reflectors receive deposits of soot and other matters which impair their capacity for reflection, and it is therefore desir' able to so mount them that they may be readily removed for the purpose of being cleaned and polished.

It is, moreover, a desideratum that reflectors thus removably mounted within lanterns, should be supported in position in such manner as not only to be maintained against dis-' placement but also as to preclude the rattling of the parts in the oscillation to which the lantern in the travel of the vehicle is subjected.

My invention aims to provide, in connection with vehicle lanterns and their reflectors, reflector-h olding or supporting devices of such character as to support thereflectors in position in the lanterns with such firmness as to preclude their displacement or rattling, and as, together with the reflector, to be easily and readily removable. R

In the accompanying drawings I show and herein I describe, forms of devices conveniently and alike embodying my invention, the particular subject-matter claimed as novel being hereinafter definitely specified.

In the accompanying drawings I illustrate my improvements as employed in connection with a vehicle lantern invented by me and forming the subject-matter of Letters Patent No. 561,816, dated June 9, 1896, and also of an application for United States Letters Patent, filed September 24, 1896, as Serial No. 606,837.

It is, however, to be understood that my improvements herein set forth are applicable in connection with vehicle andother lanterns of any character, and particularly also'those in which the combustion chamber is --verti-" cally disposed.

' In the accompanying drawings,

Figure 1 is a central, sectional, elevational view of a lantern equipped with a preferred form of my improvements.

Figure 2 is a view in perspective of the refiector shown in Figure I removed from the lantern;

Figure 3 is a view in face elevation of the reflector shown in Figures 1 and 2.

Figure 4 is a front elevational view of the lamp and contained reflector shown in Figure 1, the casing of the combustion chamber being shown in section in the plane of the dotted line 44 of said Figure 1. I

Figure 5 is a view in perspective of a reflector embodying a fundamental form of my improvements; and

Figure 6 is a similar view of a reflector embodyin g a modified form of myimprovements, in which the ends of the arms of the holder are upturned to adapt the device to be intro 'duced within a top-opening, vertically-disposed, combustion chamber.

Similar letters of reference indicate corresponding parts.

Generally stated, my invention comprehends the provision of a spring holder of substantially the character herein described and claimed, adapted to removably secure a reflector in place within a lantern.

In the drawings,

A is the combustion chamber of the vehicle lantern,-which in the form shown in Figures 1 and 2 happens to be horizontallydisposed.

B is the lamp chamber of said lamp, which serves to contain the lamp 1), the wick tube of which projects within the combustion 9o chamber; and O is the cap or chimney of the lantern, disposed above the combustion chamher which opens into it through the chimney throat c.

D is a supporting device by means of which 5 the lantern may be connected to the vehicle.

E is a swinging door, mounted in hinged relationship with respect to the-flaring mouth of the combustion chamber, and provided with the ordinary lens e;'while F is a jewelprovided light opening in the rear end wall of the combustion chamber.

G is the reflector, which may,.as stated, be of any desired character;

In Figures 1, 2, 3, and 4, of the drawings this reflector is shown as provided with a central aperture 9 in line with the rear light opening F, to render the light visible from the rear of the lantern,and said reflector is also shown as provided with a glass protecting plate g disposed in front of its silvered or reflectin g face and seated behind forward and inwardly inclined circumferential lips g mounted upon or formed as integral continuations of the body of the reflector.

The glass protecting plate may be conveniently secured beneath said lips g by means of a spring annulus G disposed in front of said protecting plate and self-retaining in position by its expansion against the inner face of said lips.

The engagement of the annulus within the lips will serve to normally retain the protecting plate securely in position, while the removal of the annulus and plate to permit of the cleaning of the face of the reflector may be conveniently effected by compressing or forcing together the outwardly'turned ends g of the annulus.

The holder H, which maybe made in a great variety of forms to suit the varying require-, 3

ments of the different forms of combustion chambers of the numerous styles of lamps manufactured, is preferably formed as a multi-armed single-piece wire structure of the general form indicated in Figures 1,2, 3, and 4, that is to say embodying four arms h 7L2 7L3 It all extending forwardly from the reflector, and all slightly divergent or having an outward spring or set, to adapt them to retain their hold against the wall of the combustion chamber within which they are en tered and slightly compressed.

I prefer to so arrange the holder that,when the reflector has been seatedin its proper position, the arms, or one or more of them,will

be seated or engaged within any suitable re- 1 to be merely forced rearwardly through the 3 combustion chamber, until the bends h oncounter the rear wall of the chamber, and the 5 locking projection engages with the chimney cess aperture or depression of the combustion chamber in order to positively lock the reflector in posit-ion and to that end, in the embodiment of my invention shown in Figures 1, 2, 3, and 4, the arms 7t 72, are shown as prolonged and merged into each other at 5 their front extremities, and as so fashioned as to constitute alocking projection k which a 5 bustion chamber having an opening formed is so located and arranged with reference to the other parts of the lantern that when the reflector is mounted in the combustion chamber said locking projection will extend up within the throat of the chimney and by contact with the forward edge of said throat prevent any undue forward movement of the reflector.

The bodies of the arms h h2 7L3 h preferably extend somewhat to the rear of the reflector, and are bent to form return bends h, which project rearwardly from said reflector, and, by contact with the rear wall of the combustion chamber, serve to maintain the reflector inproper position with relation to said rear wall and preferablyin such position that an air chamber or space is formed behind said reflector,-and which also serve to impart to the arms the desired spring set.

The holder may be conveniently secured to the reflector by the engagement of the lengths 7L7 h ,-which respectively connect the return bend of the arm h with the return bend of the arm 7?, and the return bend of the arm 7&3 with the return bend of the arm h,within lips or clips h conveniently constituted by outwardly and rearwardly curved tongues mounted on or formed as integral continuations of the marginal portion of the reflector.

It will also be understood that the arrangement of holder described, in which four arms, all formed from one continuous strand of metal and each provided with a projection 7t, and the whole secured to the reflector by the clips h, are employed,-is a preferred arrangement merely, and that these details of construction and arrangement may be omit- Thus, in Figures 5 and G, I have repre- Qsented the very simplest types of embodiment of my invention, in which the arms are separate, directly attached to the reflector, not provided with anylocking projection, and which operate to retain the reflector in position wholly by virtue of the friction of their separate expansive contact against the walls of the combustion chamber.

To remove the reflector represented in the first four figures of the drawings, from the combustion chamber, it is only necessary to open the door of the chamber, to grasp and deflect the arms If its to carry the locking projection outof engagement with the chimney throat, and, retaining said locking projection deflected, to draw the holder and reflector out through the open door.

In returning the reflector to position, it is throat.

Having thus described my invention, I

claim- 1. In combination,a lamp,embodying a comin its wall, a reflector, and a holder-for said reflector which consists of Wire spring arms at their inner ends connected with the reflector, and a locking projection formed as part ;of said reflector holder and adapted to engage in said opening in the wall of the com- 3 bustion chamber, substantially as set forth.

2. In combination,a lamp, embodyinga combustion chamber having an opening formed in its wall, a reflector, and a holder for said reflector which consists of wire spring arms attheir inner ends connected with the reflector, and a locking projection formed as part of said reflector holder and as a continuation of two of said arms and adapted to engage in said opening in the wall of the' combustion chamber, substantially as set forth.

3. In combination, a lamp, a reflector, and a holder for said reflector which consists of a series of spring arms at their inner ends connected with the reflector, and as to their bodies extending away from it, and at its rear formed with return bends which are adapted to make contact With the rear wall of the combustion chamber, substantially as set forth.

4:. In combination, a lantern or lamp, a reflector, and a holder for said reflector which consists of a series of wire arms disposed in substantial parallelism with the axis of the reflector, extending to the front and rear of said reflector, at the rear provided with return bends which are connected to the marginal portion of the reflector, and at the front diverging from each other, substantially as set forth.

5. In combination alautern or lamp, a reflector, and a holder for said reflector which consists of a series of Wire arms disposed in substantial parallelism with the axis of the reflector, extending to the front and rear of said reflector, at the rear provided with return bends which are connected to the marginal portion of the reflector, and at the front diverging from each other, and the front or forward extremity of one of which is equipped with or formed into a locking projection adapted in the predetermined set of the parts to expand to place within a suitable recess in the body of the lantern, substantially as set forth.

In testimony that I claim the foregoing as my invention I have hereunto signed my name this 4th day of November, A. D. 1897.
